The View Composer database used for linked clones is backed up using the following steps:
Log in to the View Administrator console.
Expand the Catalog option under Inventory (left-hand side of the console).
Select the first pool and right-click on it.
Select Disable Provisioning.
Connect directly to the server where the View Composer was installed, using a remote desktop utility such as RDP.
Stop the View Composer service, as shown in the following screenshot. This will prevent provisioning request that would change the composer database.
After the service is stopped, use the standard practice for backed up databases in the current environment. Restart the Composer service after the backup completes.
